Frazer or Frazier I did some more searching and found a Abner Frazier d. 25 Sep 1907 and buried in Los Angeles National Cemetery. I'm not convinced that this is the right person. You could check that out yourself.
RE: Amos Newton and Edward M. Frazer Hello Annalee - I'm afraid I don't know anything about the birth dates of these fellas, nor do I know the whereabouts of your missing Frazers (they do not appear in the listing for AG Cemetery at http://www.slocgs.org). Did you also contact the manager of Amos's memorial? She might have some information.
